Question

For the cell (at 298 K) Ag(s) | AgCl(s) | Cl- (aq) || AgNO3 (aq) | Ag(s)
Which of following is correct -

Options

A.The cell emf will be zero when [Ag+]a = [Ag+]c ([Ag+] in anodic compartment = [Ag+] in cathodic compartment)
B.The amount of AgCl(s) precipitate in anodic compartment will decrease with the working of the cell.
C.The concentration of [Ag+] = constant, in anodic compartment during working of cell.
D.Ecell = EoAg+/Ag - EoCl-|AgCl|Ag -

Solution

ECell = EoCell - ; At [Ag+]c = [Ag+]a equilibrium will achieve and K = Ksp = [Ag+]a[Cl-]a
